Configuring the Restore and Recovery Setting for Your IP Resource
Field Tips
Replication
Path
Select the pair of local and remote IP addresses to use for replication between
the target server and the other indicated server in the cluster. The valid paths
and their associated IP addresses are derived from the set of LifeKeeper
communication paths that have been defined for this same pair of servers. Due
to the nature of DataKeeper, it is strongly recommended that you use a private
(dedicated) network.
If the DataKeeper Resource has previously been extended to one or more target
servers, the extension to an additional server will loop through each of the
pairings of the new target server with existing servers, prompting for a
Replication Path for each pair.
Replication
Type
Choose “synchronous” or “asynchronous” to indicate the type of replication
that should be used between the indicated pair of servers.
As for the previous Replication Path field, if the DataKeeper Resource has
previously been extended to one or more target servers, the extension to an
additional server will loop through each of the pairings of the new target server
with existing servers, prompting for a Replication Type for each pair.
2. Click Next to continue. An information box will appear verifying that the extension is being
performed.
3. Click Finish to confirm the successful extension of your DataKeeper resource instance.
4. Click Done to exit the Extend Resources Hierarchy menu selection.
Configuring the Restore and Recovery Setting for Your
IP Resource
To complete this configuration, you will need configure the Restore and Recovery setting for your IP
resource to Disable. This option is displayed in the Properties pane. When the Properties pane is
open for an IP resource or the properties for an IP resource are being displayed, this setting is one of
three button options. Refer to the IP Recovery Kit for more information regarding this option.
Note: Be sure to test the functionality of the new instance on all servers by performing a manual
switchover. See Testing Your Resource Hierarchy for details. At this point, SteelEye DataKeeper
has initiated the data resynchronization from the source to the target disk or partition once the extend
to the disaster recovery node is completed. In the LifeKeeper GUI, the state of the DataKeeper
resource on the target server is set to “Resyncing”. Once the resynchronization is complete, the
state will change to “Target” which is the normal Standby condition.
During resynchronization, the DataKeeper resource and any resource that depends on it will not be
able to fail over. This is to avoid data corruption.
If you haven’t done so already, make sure you set the confirm failover flags. Refer to the section
Confirm Failover and Block Resource Failover Settingsfor more information about this procedure.
